ClrMamePro is a so called ROM-manager. It's mainly programmed for M.A.M.E. the Multi-Arcade-Machine-Emulator. If you want to know more about this program you should visit its homepage.

However, ClrMamePro can also be used with other emulator files. Therefore once you've download the GP32 Frodo dat, you can use CMP to scan your own private Commodore 64 Games collection and put aside the versions that are compatible with GP32 Frodo.
